Effects of B‐Site Nb Substitution on ORR Activity in Perovskite Cathode Materials for Solid Oxide Fuel Cells

open access: yesSusMat, EarlyView.
B‐site Nb substitution in PSCF perovskite cathodes modulates oxygen vacancy formation and electronic structure, thereby tailoring oxygen adsorption and ion transport properties. A moderate Nb level (5–10%) optimizes the balance between surface activity and conductivity, enhancing ORR kinetics and SOFC performance. ABSTRACT Solid oxide fuel cells (SOFCs)

A novel circumscription and classification for Neurolaeneae (Asteraceae)

open access: yesTAXON, EarlyView.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...
